Editorial records can be verified in two different ways:
Sending editorial decision letters to firstname.lastname@example.org both adds the editorial record and verifies it. This is by far the simplest way to add editorial records to Publons.
Via journal integration
At this point there are no automatic links between review submission systems and Publons which facilitate creation of editorial records. However, partnered journals can still verify editorial records via their partner dashboard. If you have unverified editorial records on your profile for a partnered journal, reach out to their administrative office to request they verify those records from the partner dashboard.
